Question 1 of 5
what is the route of INSULIN GLARGINE:
Correct Answer: A
Rationale: Insulin glargine is a type of long-acting insulin that is given via subcutaneous injection. Subcutaneous administration involves injecting the medication into the fatty tissue layer just beneath the skin. This route allows for slow and consistent absorption of the insulin into the bloodstream, providing a prolonged effect on lowering blood sugar levels. Insulin cannot be taken orally because it would be broken down by the digestive system before it could be effective. Intravenous (IV) administration is also not appropriate for insulin glargine because it is meant to have a slow, sustained release in the body, which cannot be achieved with IV administration. Sublingual administration, where a medication is placed under the tongue for absorption, is not suitable for insulin as it requires specific pathways for absorption that are not present under the tongue.
Question 2 of 5
Which of the following medications is known to act on the Renin-Angiotensin- Aldosterone System (RAAS), in order to prevent the conversion of angiotensin I to the angiotensin II?
Correct Answer: A
Rationale: ACE (Angiotensin-Converting Enzyme) inhibitors are known to act on the Renin-Angiotensin-Aldosterone System (RAAS) by blocking the conversion of angiotensin I to the active angiotensin II. Angiotensin II is a potent vasoconstrictor and also stimulates the release of aldosterone, leading to increased blood pressure. By inhibiting ACE, ACE inhibitors help to lower blood pressure and reduce the secretion of aldosterone, thereby decreasing the overall vasoconstriction and volume expansion effects of the RAAS. Examples of ACE inhibitors include medications such as lisinopril, enalapril, and captopril.
Question 3 of 5
Hemostatic agents that arrest the flow of blood from small vessels by precipitating the tissue proteins in the immediate area:
Correct Answer: B
Rationale: Styptics and astringents are hemostatic agents that work by precipitating tissue proteins in the immediate area of a small vessel to stop bleeding. Styptics such as alum, silver nitrate, and ferric subsulfate directly induce coagulation at the site of bleeding, forming a protective scab to stop the flow of blood. Astringents like tannic acid work by tightening the tissue proteins around the blood vessel to create a seal and halt bleeding. These agents are commonly used in the management of minor cuts and wounds to promote hemostasis.
Question 4 of 5
In Fried's rule of dosage calculation, it is the number of months a child has reached an age when an adult dose can be tolerated>
Correct Answer: C
Rationale: In Fried's rule for dosage calculation, the formula is to divide the child's age in months by 150 to find the fraction of adult dose that can be tolerated. Generally, a child is considered to tolerate an adult dose when they have reached 12 months of age. This is based on the assumption that a 12-month-old child can typically tolerate a dose similar to that of an adult. Therefore, the correct answer is 12 months, which is option C.
Question 5 of 5
A patient taking isoniazid is worried about the negative effects of the drug. The nurse provides information knowing that which is an adverse effect of the drug?
Correct Answer: B
Rationale: Isoniazid is associated with hepatotoxicity, which can range from asymptomatic elevation of liver enzymes to severe hepatitis. Patients should be monitored for symptoms such as fatigue, nausea, and jaundice. Ototoxicity and nephrotoxicity are not common adverse effects of isoniazid. Optic neuritis is a rare side effect of ethambutol, another antitubercular drug, not isoniazid.
